Frequently asked questions
Annual US Consumer Price Index values from 1980 to 2024, indexed so that 1982 to 1984 equals 100. The 2024 value is an estimate, so results can differ slightly from official monthly figures.
The amount is multiplied by the end year's CPI divided by the start year's CPI. With 172.2 for 2000 and 314.0 for 2024, $100 in 2000 is $182.35 in 2024.
Yes. Choose an end year earlier than the start year to express a recent amount in older dollars. The cumulative inflation then shows as a negative percentage.
The arithmetic works for any amount, but the index is US data, so the result only reflects US price changes. For another country, apply that country's price index with the same formula.
